Clearwire may begin testing hardware that enables even faster mobile broadband technology, thus far simply dubbed WiMAX 2, as early as 2011, according to the data provider's CTO. The 802.16m specification should be approved this summer by the IEEE and is expected to bring with it 120Mbps download and 60Mbps upload speeds in urban environments using 4x2 MIMO antennas. These numbers are about twice of what lab tests show for current WiMAX tech.
